Correct, assuming that the relay host has a different IP in each subnet. It is probably working because you have mostly reserved. I assume that the dynamic pool is only in one subnet, so a device connected to another subnet would not be able to work if it got a dynamic address, because it would be the wrong IP address and router (gateway) address.
